Taurine, an amino acid obtained from the diet, commonly found in a variety of meats, dairy products and eggs. Unfortunately, physical activity depletes our taurine reserves faster than most people can produce it. Vegetarians, athletes and individuals that lack meat in their diet, stand to benefit the most from supplementing this nutrient. Taurine is a key constituent of bile acids; it helps the body absorb other nutrients with greater ease while moderating healthy cellular activity. It has also been known to have antioxidant properties that may protect macular regions of the eye.
